Abstract

This relates to an improved process for the preparation of uncatalyzed (fluoro)silicone rubber bases which are prepared by the introduction of reinforcing fillers into high viscosity (i.e., greater than 1 million mPa.s at 25°C) silicone polymers and/or high viscosity (i.e., greater than 1 million mPa.s at 25°C) fluorosilicone polymers (often referred to in the industry as silicone polymer gums and fluorosilicone polymer gums respectively) and their copolymers, optionally in the presence of filler treating agents which are utilised in situ to render said fillers hydrophobic. The uncatalyzed silicone rubber bases are then further mixed with one or more catalysts/vulcanising agents as well as cross-linkers, when required and optionally a variety of additives to form curable one-part or multi-part silicone rubber compound compositions. This also relates to the silicone elastomers made by curing said curable one-part or multi-part silicone rubber compound compositions.

Abstract

Methods for forming light olefins in a reactor system may include reacting a feed stream in the presence of a particulate solid in a reactor to form a product stream. The reaction may form coke on the particulate solid. The method may include passing the particulate solid to the regenerator and burning at least a portion of the coke to heat the particulate solid; mixing air and supplemental fuel upstream of the regenerator to form a gas mixture and passing the gas mixture to the regenerator through a distributor; and combusting the supplemental fuel in the regenerator to heat the particulate solid; and passing the heated particulate solid from the regenerator to the reactor. A concentration of supplemental fuel in the gas mixture may be less than 80% of the lower explosive limit of the supplemental fuel in the gas mixture, and heat from burning the coke and the supplemental fuel may be sufficient to maintain a heat balance of the reactor system.

Abstract

Embodiments of the present disclosure are directed towards a heterogenous catalyst composition of formed from using a crystalline porous metal-organic framework (MOF) which reacts in an inverse electron-demand Diels-Alder reaction with a phosphorous ligand to produce a heterogeneous catalyst precursor. The heterogeneous catalyst precursor then reacts with a Group VIII transition metal catalyst precursor compound to form the heterogeneous catalyst composition that can be used for the hydroformylation of olefins, among other reactions.

The outer skirt may include a wall disposed radially around a periphery of the base and the grid distributor. The base, the grid distributor, the solids transport passage, and the outer skirt define an annular region between the outer skirt and the solids transport passage. The fluid inlet extends through the base. The fluid director is disposed within the annular region and is shaped to direct a fluid from the fluid inlet into the annular region in a fluid direction that is substantially tangential to the outer skirt. Also disclosed herein are methods of operating a chemical processing vessel.

Abstract

Alkoxylations are performed by reacting a cyclic oxide with a starter in the presence of certain phosphonium catalysts. The phosphonium catalysts are highly active and effective in such small quantities that it is often unnecessary to remove catalyst residues from the product. The phosphonium catalysts are very effective in alkoxylating even low molecular weight starters such as glycerol and sorbitol.

Abstract

Disclosed herein are methods of improving the restart performance of a high-selectivity ethylene oxide catalyst that has been shut down due to a planned or unplanned outage. It is believed that the proper selection of process variables on restart avoids exacerbating catalyst surface overchloriding that may occur when subsurface chlorides are diffused to the catalyst surface. In accordance with the method, the initial restart reaction temperature is no more than five (5) degrees Celsius above an initial start-up steady-state reaction temperature on fresh catalyst and is no more than five (5) degrees Celsius below the initial start-up steady-state reaction temperature. The addition of a make-up organic chloride to the reactor feed gas is deferred until the reactor outlet oxygen concentration equals or exceeds 0.5 mole percent and until a relative scaled reactor vinyl chloride feed gas concentration is no greater than 110 percent.

Abstract

The invention is a process for making molded polymer foams, especially laminated panels that include a central foam layer and a facing layer on one or both sides. A flexible film dispenser (10) is folded or rolled and introduced into a mold cavity (7) through an opening (6) in the mold. The dispenser is unfolded or unrolled inside the film cavity and a foam precursor is pumped through the dispenser and into the mold cavity. The dispenser has multiple outlets (16) through which the foam precursor enters the mold cavity. This permits a more uniform distribution of the foam precursor throughout the mold cavity and reduces defects while improving product quality.

Abstract

Methods for producing an aqueous polyolefin dispersion comprise providing a partially neutralized ionomer dispersant, which is an ethylene acid copolymer comprising the polymerized reaction product of 70 to 85 wt.% ethylene and 15 to 30 wt.% carboxylic acid containing comonomer, based on the total weight of monomers present in the ethylene acid copolymer, of which 0.01 to 30 mole % of the acid units are neutralized by alkali metal cations based on the total weight of monomers present in the ethylene acid copolymer. The methods further comprise melt blending the partially neutralized ionomer dispersant and polyolefin to produce a polymer melt blend, emulsifying the polymer melt blend in the presence of water and additional base to produce an emulsion, wherein the additional base further neutralizes a fraction or all of the remaining acid units, and diluting the emulsion with additional water to produce the aqueous polyolefin dispersion.

Abstract

A bicomponent fiber comprising a first component and a second component is currently disclosed. The first component is comprised of from 70 to 97.5 wt.%, based on the weight of the first component, a polyethylene having a melt index, and from 2.5 to 30 wt.%, based on the weight of the first component, of a maleic-anhydride-grafted polyethylene having a maleic-anhydride level of from 0.50 to 3.00 wt.%, based on the weight of the maleic-anhydride-grafted polyethylene, and a melt index. The ratio of the melt index of the polyethylene to the melt index of the maleic-anhydride-grafted polyethylene is less than 1.25. The first and second components can be part of a core sheath, an eccentric core sheath, an islands in the sea, a side by side, or a segmented-pie structure. The disclosed bicomponent fibers can be used to produce nonwoven materials. These bicomponent fibers can produce nonwovens with improved bonding efficiency and better mechanical strength due to increased surface concentration of maleic anhydride as evidenced by a higher surface oxygen concentration.

Abstract

Embodiments of an extruder comprise an extruder housing having an internal wall and a single screw coaxially disposed within the extruder housing, the single screw comprising a shank, wherein the shank and/or a region of the internal wall proximate the shank comprises helical channels. The extruder further comprises a feed channel downstream of the shank, and a visco-seal comprising the helical channels and the annular gap between the shank and the internal wall, wherein the annular gap is variable across its length.

IPC Classes  ?
